DETAILED DESCRIPTION

[0034] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0035] like Figures 1 to 12 A ceramic antenna that is easy to use outdoors is shown, including a vertical pole 1, an antenna cover 3 is fixed on the outer wall of the vertical pole 1, a base 4 is fixedly installed on the bottom of the antenna cover 3, a mounting plate 2 is fixed on the outer wall of the vertical pole 1, a buffer assembly is arranged on the top of the mounting plate 2, the buffer assembly is used to support and reinforce the base 4, a clamping mechanism for fixing the antenna feed line is arranged at the bottom of the mounting plate 2, an ultrasonic generator 9 is fixed on the top of the mounting plate 2, a box is fixed on the outer wall of the bottom of the vertical pole 1, and a controller is arranged inside the box.

[0036] It should be noted that an antenna array unit is disposed inside the antenna cover 3. The antenna system composed of many identical single ceramic antennas arranged in a certain pattern is also called an antenna array.

[0037] A remote radio frequency unit is arranged inside the box, which is the baseband processing unit of the base station. The top of the antenna feed line is connected to the bottom of the antenna array unit, and the bottom of the antenna feed line is connected to the remote radio frequency unit inside the box.

[0038] In a specific implementation process, a plurality of support rods are fixed in a circular array on the outer wall of the vertical rod 1, and the bottom ends of the support rods are fixedly connected to the ground.

[0039] Specifically, because 5G base stations are located outdoors all year round, the influence of wind will cause the antenna to tilt and the feed line to shake, which will cause the connection between the antenna and the feed line to loosen and cause poor contact. At the same time, the bird droppings produced by birds building nests on the feed line will also corrode the connection between the feed line and the antenna, causing the connection between the feed line and the antenna to loosen.

[0040] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows. First, the wind blowing on the outer wall of the antenna cover 3 will generate an impact force on the antenna cover 3, so that the antenna cover 3 has a tendency to tilt. The buffer component provided can support the base 4. By supporting the base 4, the base 4 can give the antenna cover 3 a supporting force to offset the impact force, which is beneficial to maintaining the stability of the antenna cover 3, and further beneficial to maintaining the stability of the connection between the antenna cover 3 and the antenna feed line, and preventing the connection between the antenna cover 3 and the antenna feed line from bending due to the tilt of the antenna cover 3.

[0041] At the same time, wind blowing on the antenna feed line will cause the antenna feed line to shake. The clamping mechanism can fix and clamp the end of the antenna feed line close to the antenna, which is beneficial to prevent the end of the antenna feed line close to the antenna from shaking, thereby maintaining the stability of the connection between the antenna feed line and the antenna cover 3.

[0042] The ultrasonic generator 9 can continuously emit high-frequency ultrasonic waves to stimulate the nervous system of birds and destroy their living environment, so that the birds are kept away from the coverage area, thereby preventing the birds from staying on the antenna feed line and causing the antenna feed line to shake, and preventing the birds from building nests above the mounting plate 2.

[0043] By maintaining the stability of the connection between the antenna cover 3 and the antenna feed line, it is helpful to prevent the connection between the antenna feed line and the antenna from becoming loose.

[0044] In the further implementation process, the buffer assembly includes two slide rails 6, and the two slide rails 6 are symmetrically fixed on the top of the mounting plate 2. The top of the mounting plate 2 is slidably connected to two slide plates 7, and the two slide plates 7 are respectively located on both sides of the base 4. The slide plates 7 are slidably connected to the two slide rails 6. The two slide plates 7 are fixed with protrusions on one side close to the base 4, and the side walls of the protrusions are fitted with the side walls of the base 4. Elastic telescopic rods 8 are symmetrically fixed between the two slide plates 7.

[0045] In a specific implementation process, the elastic telescopic rod 8 is in a stretched state, and the tension generated by the elastic telescopic rod 8 acts on the two slide plates 7 .

[0046] Specifically, the two slides 7 are respectively located on both sides of the base 4. Under the pulling force of the elastic telescopic rod 8, the two slides 7 are pressed against both sides of the base 4 to provide support for the base 4. Through the provided protrusions, the inclined surface of the protrusions is in contact with the side walls of the base 4. After the antenna cover 3 is subjected to an impact force which is transmitted to the base 4, the pulling force of the elastic telescopic rod 8 can offset the impact force on the antenna cover 3, which is beneficial to maintaining the stability of the antenna cover 3.

[0047] In a further implementation process, the clamping mechanism includes a vertical plate 10, which is fixed at the bottom of the mounting plate 2. A plurality of clamps 11 are fixed in a linear array on one side of the vertical plate 10. The number of the clamps 11 corresponds one to one with the number of antenna feed lines. The clamps 11 are used to fix and clamp the antenna feed lines. A U-shaped frame 12 is fixed at the bottom of the mounting plate 2. A plurality of limit assemblies are provided in a linear array on the top of the U-shaped frame 12. The limit assemblies are used to reduce the shaking amplitude of the antenna feed lines.

[0048] It should be noted that an opening is provided through the top of the mounting plate 2 , and the top of the antenna feed line passes through the opening and is connected to the bottom of the antenna cover 3 .

[0049] Specifically, the antenna feed line is fixedly clamped by the clamping hoop 11, which can prevent the shaking of the antenna feed line from affecting the end close to the antenna cover 3, thereby helping to maintain the stability of the connection between the antenna cover 3 and the antenna feed line. A limiting component is arranged under the clamping hoop 11. The limiting component can further reduce the shaking amplitude of the antenna feed line, which is beneficial to reducing the wear between the antenna feed line and the clamping hoop 11, and preventing the outer wall of the antenna feed line from being damaged due to friction.

[0050] In the further implementation process, the limiting assembly includes a fixed block 13, which is fixed on the top of the cross bar part of the U-shaped frame 12. A cylinder 14 is fixed on the side of the fixed block 13 close to the antenna feed line, and a cavity is opened inside the cylinder 14. The end of the cylinder 14 is slidably connected with a first round rod 15. Both ends of the first round rod 15 are located outside the cylinder 14. A ring 16 is fixed at one end of the first round rod 15 close to the antenna feed line. The ring 16 is sleeved on the outside of the antenna feed line. A fixing ring 17 is fixed on the outer wall of the first round rod 15. The fixing ring 17 is located inside the cavity. A damping spring 18 is fixed on one side of the fixing ring 17. The end of the damping spring 18 away from the fixing ring 17 is fixedly connected to the inner wall of the cavity, and the damping spring 18 is sleeved on the outer wall of the first round rod 15.

[0051] Specifically, when the antenna feed line shakes, the antenna feed line drives the sleeved ring 16 to move, and the ring 16 drives the first round rod 15 to move. When the antenna feed line moves in a direction away from the first round rod 15, the damping spring 18 can be stretched during the movement of the first round rod 15. When the antenna feed line moves in a direction close to the first round rod 15, the damping spring 18 can be compressed during the movement of the first round rod 15. Under the action of the elastic force of the damping spring 18, the moving distance of the ring 16 can be reduced, thereby reducing the shaking amplitude of the antenna feed line, thereby reducing the wear between the antenna feed line and the clamp 11 when the antenna feed line shakes.

[0052] In a further implementation process, a second round rod 19 is fixed between the two vertical parts of the U-shaped frame 12, a plurality of bamboo tubes 20 are rotatably connected to the outer wall of the second round rod 19 in a linear array, a plurality of limit blocks 22 are fixed to the outer wall of the second round rod 19, both sides of the bamboo tube 20 are provided with limit blocks 22, and a connecting block 21 is fixed to the bottom end of the bamboo tube 20;

[0053] A groove 23 is provided at the top of the mounting plate 2, and a plurality of drain pipes 24 are fixed in a linear array at the bottom of the mounting plate 2. The top of the drain pipe 24 passes through the side wall of the mounting plate 2 and is connected to the inside of the groove 23, and the bottom of the drain pipe 24 is located directly above the water inlet of the bamboo tube 20.

[0054] In the specific implementation process, a plurality of guide grooves are provided in a linear array on the top of the mounting plate 2 , the guide grooves are connected to the inside of the groove 23 , a filter screen is provided on the top of the drain pipe 24 , and a water tank is provided on the top of the bamboo tube 20 .

[0055] Specifically, in rainy and snowy weather, rainwater on the top of the mounting plate 2 and melted snow water can enter the interior of the groove 23 through the guide groove, and then pass through the filter screen into the interior of the drain pipe 24. The filter screen can intercept larger debris to prevent the debris from clogging the drain pipe 24. The water flowing out from the drainage end of the drain pipe 24 falls vertically into the water tank inside the bamboo tube 20. As the weight of the head of the bamboo tube 20 increases, when the water tank at the top of the bamboo tube 20 is filled with water, the top of the bamboo tube 20 naturally droops to empty the water in the water tank, and then returns to its original position under the action of the gravity of the tail. The tail drives the connecting block 21 to impact on the first round rod 15, causing the first round rod 15 to move a short distance, and then reset under the action of the damping spring 18.

[0056] The first round rod 15 drives the circular ring 16 to move, and the circular ring 16 drives the antenna feed line to move. The movement of the first round rod 15 has the effect of slightly shaking the antenna feed line. When it rains, slightly shaking the antenna feed line is conducive to making the rainwater attached to the antenna feed line slide off quickly, which is conducive to reducing the risks of leakage and short circuit. When it snows, slightly shaking the antenna feed line can shake off the snow accumulated on the antenna feed line, preventing the snow from accumulating on the antenna feed line and increasing the weight of the antenna feed line, which is conducive to preventing the antenna feed line and the clamp 11 from sliding relative to each other due to the excessive weight of the antenna feed line. At the same time, it can also help prevent the snow water generated by the melting snow pile from freezing on the outer wall of the antenna feed line.

[0057] It should be noted that the debris specifically includes garbage floating on the mounting plate 2 and small snowballs and ice cubes that have not melted on snowy days. The head of the bamboo tube 20 is the end with the water tank, and the tail of the bamboo tube 20 is the end connected to the connecting block 21.

[0058] In a further implementation process, a guide groove 25 is fixed on the top of the fixing block 13 , and the bottom of the guide groove 25 is fixedly connected to the outer wall of one end of the cylinder 14 close to the ring 16 , and the guide groove 25 is located directly below the bamboo tube 20 .

[0059] Specifically, the high-frequency ultrasonic wave generated by the ultrasonic generator 9 can act on the antenna feed line, which helps to shake off the dust attached to the antenna feed line. Through the provided guide groove 25, after the water tank at the top of the bamboo tube 20 is filled with water, the top of the bamboo tube 20 naturally droops to empty the water in the water tank. The water poured out of the bamboo tube 20 enters the guide groove 25 and is poured onto the outer wall of the antenna feed line along the guide groove 25, which can flush the antenna feed line and further promote the cleaning of the outer wall of the antenna feed line. At the same time, on snowy days, flushing the antenna feed line can also speed up the cleaning of snow piles on the antenna feed line.

[0060] In the further implementation process, an installation cavity is opened inside the installation plate 2, and a motor 26 is arranged inside the installation cavity. A rotating rod 27 is fixed to the output shaft of the motor 26. The end of the rotating rod 27 away from the motor 26 passes through the inner wall of the installation cavity and is rotatably connected to the inner wall of the groove 23. A plurality of stirring rods 28 are fixed in a linear array on the outer wall of the rotating rod 27, and a rain and snow sensor 35 is arranged on the top of the installation plate 2.

[0061] In the specific implementation process, the rain and snow sensor 35 is connected to the controller for communication, and the controller is connected to the motor 26 for communication. The rain and snow sensor 35 is a qualitative measurement device for measuring whether it is raining or snowing outdoors or in nature. It is a prior art and will not be described here.

[0062] Specifically, through the rain and snow sensor 35, when snow falls on the sensing area of ​​the rain and snow sensor 35, the rain and snow sensor 35 generates snowfall information and sends the snowfall information to the controller. The controller generates first control information according to the snowfall information, and sends the first control information to the motor 26 to control the start of the motor 26. After the snow stops, when no snow falls on the sensing area of ​​the rain and snow sensor 35 for a period of time, the rain and snow sensor 35 generates snow stop information and sends the snow stop information to the controller. The controller generates second control information according to the snow stop information, and sends the second control information to the motor 26 to control the motor 26 to stop moving.

[0063] The motor 26 drives the rotating rod 27 to rotate, and the rotating rod 27 drives multiple stirring rods 28 to rotate synchronously. The stirring rods 28 stir the inside of the groove 23, so as to stir the snow inside the groove 23 and accelerate the melting of the snow into water. At the same time, it is also beneficial to prevent the snow accumulated inside the groove 23 from freezing and clogging the filter screen, which is beneficial for water to flow smoothly from the drain pipe 24 into the inside of the bamboo tube 20.

[0064] In the further implementation process, a groove is opened on the top of the base 4, and the airbag 5 is fixedly installed inside the groove. An air replenishing component is arranged inside the mounting plate 2, and the air replenishing component is used to inflate the interior of the airbag 5. An exhaust port is opened on one side of the top of the airbag 5, and a pressure relief valve is arranged inside the exhaust port. An air pressure sensor 36 is arranged inside the airbag 5.

[0065] Specifically, through the airbag 5, after the external wind blows and impacts the antenna cover 3, the airbag 5 can play a vibration reduction role and reduce the vibration generated by the antenna cover 3, thereby providing a vibration reduction function for the multiple ceramic antennas inside the antenna cover 3. The airbag 5 can also seal the gap between the antenna cover 3 and the base 4, which is beneficial to prevent external dust and rainwater from penetrating into the interior of the antenna cover 3 through the gap between the antenna cover 3 and the base 4, thereby facilitating the normal operation of the ceramic antenna inside the antenna cover 3.

[0066] The top of the airbag 5 is located above the groove, and the high-frequency ultrasonic wave generated by the ultrasonic generator 9 can shake off the dust on the surface of the airbag 5. In rainy and snowy weather, the high-frequency ultrasonic wave generated by the ultrasonic generator 9 can also accelerate the melting of snow and the rapid evaporation of water, which is beneficial to reduce the impact of rainwater adhering to the outer wall of the antenna cover 3 on the signal.

[0067] By means of the air pressure sensor 36 provided inside the airbag 5, the air pressure inside the airbag 5 can be monitored in real time. After the air pressure inside the airbag 5 is lower than the set value, the air pressure sensor 36 generates first air pressure information, and sends the first air pressure information to the controller. The controller generates third control information based on the first air pressure information, and sends the third control information to the air replenishing component to control the air replenishing component to start replenishing air to the airbag 5. After the air pressure sensor 36 detects that the air pressure inside the airbag 5 rises from the set value to the maximum value, the air pressure sensor 36 generates second air pressure information, and sends the second air pressure information to the controller. The controller generates fourth control information based on the second air pressure information, and sends the fourth control information to the air replenishing component to control the air replenishing component to stop moving.

[0068] It should be noted that the set value is the air pressure value set by the staff for the air pressure sensor 36, and the set value must be smaller than the maximum value. The maximum value is the maximum value of the internal air pressure when the airbag 5 is working normally. If it is higher than the maximum value, the airbag 5 will be damaged.

[0069] In the further implementation process, the air replenishing component includes a mounting groove, which is opened at the bottom of the mounting plate 2. The end of the rotating rod 27 away from the motor 26 passes through the side wall of the mounting groove. The end of the rotating rod 27 enters the interior of the mounting groove and is fixed with a disc 29. A connecting rod 32 is rotatably connected to the side wall of one side of the disc 29 through a pin. A piston cylinder 30 is fixed on the inner wall of the groove. A sliding block 31 is slidably connected to the inside of the piston cylinder 30. The end of the connecting rod 32 away from the disc 29 is rotatably connected to the sliding block 31.

[0070] A first air inlet pipe 33 is fixedly connected to the outer wall of the piston cylinder 30, and the end of the first air inlet pipe 33 away from the piston cylinder 30 passes through the inner wall of the mounting plate 2 and the base 4. The end of the first air inlet pipe 33 away from the piston cylinder 30 is fixedly connected to the interior of the airbag 5, and a first one-way valve is arranged inside the first air inlet pipe 33. A second air inlet pipe 34 is fixedly connected to the outer wall of the piston cylinder 30, and a second one-way valve is arranged inside the second air inlet pipe 34.

[0071] In the specific implementation process, through the first one-way valve, the gas inside the piston cylinder 30 can pass through the first one-way valve to enter the first air intake pipe 33, and the gas inside the first air intake pipe 33 cannot pass through the first one-way valve to enter the piston cylinder 30.

[0072] Through the second one-way valve, the external air can pass through the second one-way valve to enter the interior of the piston cylinder 30, and the gas inside the piston cylinder 30 cannot pass through the second one-way valve to be discharged to the outside.

[0073] Specifically, after the air pressure sensor 36 detects that the air pressure inside the airbag 5 is lower than the set value, the air pressure sensor 36 generates first air pressure information and sends the first air pressure information to the controller. The controller generates third control information based on the first air pressure information and sends the third control information to the motor 26. The motor 26 drives the rotating rod 27 to rotate, and the rotating rod 27 drives the disk 29 to rotate. The rotation of the disk 29 drives the connecting rod 32 to move, and the connecting rod 32 drives the sliding block 31 to reciprocate inside the piston cylinder 30.

[0074] When the sliding block 31 moves toward the position of the disk 29, the air pressure inside the piston cylinder 30 decreases, and the outside air enters from the second air inlet pipe 34 and passes through the second one-way valve, and finally enters the interior of the piston cylinder 30. Then the sliding block 31 moves in the direction away from the disk 29, squeezing the gas inside the piston cylinder 30. After the air pressure inside the piston cylinder 30 increases, the gas passes through the first one-way valve along the first air inlet pipe 33 and enters the interior of the airbag 5, thereby replenishing the air in the airbag 5. Through the provided pressure relief valve, when the air pressure inside the airbag 5 is higher than the maximum value, the gas inside the airbag 5 can pass through the pressure relief valve and be discharged to the outside, so as to prevent the air pressure inside the airbag 5 from being too high, causing damage to the airbag 5.

[0075] After the air pressure sensor 36 detects that the air pressure inside the airbag 5 rises from the set value to the maximum value, the air pressure sensor 36 generates second air pressure information and sends the second air pressure information to the controller. The controller generates fourth control information based on the second air pressure information and sends the fourth control information to the air replenishing component to control the air replenishing component to stop moving.

[0076] Working principle of the present invention:

[0077] When the present invention is in use, first, the staff uses the pulling force of the two elastic telescopic rods 8 to clamp the two slides 7 on both sides of the base 4 to provide support for the base 4, which is beneficial to maintaining the stability of the antenna cover 3. Then the staff uses the clamp 11 to fix and clamp the end of the antenna feed line close to the antenna cover 3, which is beneficial to maintain the stability of the end of the antenna feed line close to the antenna cover 3, thereby maintaining the stability of the connection between the antenna cover 3 and the antenna feed line, and reducing the possibility of loosening at the connection between the antenna cover 3 and the antenna feed line.

[0078] When the antenna feed line shakes under the action of wind, the antenna feed line drives the ring 16 to move, and the ring 16 drives the first round rod 15 to squeeze or stretch the damping spring 18. Under the elastic force of the damping spring 18, the movement distance of the ring 16 can be reduced, and then the shaking amplitude of the antenna feed line can be reduced, which is beneficial to reduce the wear between the antenna feed line and the clamp 11. At the same time, the stability of the end of the antenna feed line close to the antenna cover 3 is further improved. The high-frequency ultrasonic wave generated by the ultrasonic generator 9 can drive away birds and prevent the bird droppings produced by birds nesting on the antenna feed line from corroding the antenna feed line.

[0079] The rain and snow sensor 35 is provided to detect whether it is raining or snowing. In rainy and snowy weather, rainwater or melted snow water on the top of the mounting plate 2 can pass through the filter screen into the drain pipe 24, and then fall vertically from the bottom water outlet of the drain pipe 24 into the water tank inside the bamboo tube 20. The reciprocating swing of the bamboo tube 20 drives the connecting block 21 to impact the first round rod 15, and the first round rod 15 drives the circular ring 16 to move, which has the effect of slightly shaking the antenna feed line. The water poured out of the bamboo tube 20 is poured onto the outer wall of the antenna feed line along the guide groove 25.

[0080] When it rains, slightly shaking the antenna feed line can shake off the dust on the antenna feed line, which is beneficial to the cleaning of the antenna feed line. The water poured out of the bamboo tube 20 rinses the outer wall of the antenna feed line, further improving the efficiency of cleaning the antenna feed line. At the same time, slightly shaking the antenna feed line is beneficial to make the rainwater attached to the antenna feed line slide off quickly, which is beneficial to reduce the risk of leakage and short circuit. The high-frequency ultrasonic wave generated by the ultrasonic generator 9 can accelerate the vibration of rainwater, further promoting the rapid sliding of rainwater from the antenna feed line.

[0081] When it snows, shaking the antenna feed line can shake off the snow accumulated on the antenna feed line to prevent the snow from accumulating on the antenna feed line and increasing the weight of the antenna feed line, thereby causing relative sliding between the antenna feed line and the clamp 11. The water poured out from the bamboo tube 20 rinses the outer wall of the antenna feed line, further speeding up the cleaning of the snow pile on the antenna feed line.

[0082] By means of the motor 26, when it snows, the motor 26 drives the stirring rod 28 to stir the snow pile, which is beneficial to the rapid melting of the snow pile, thereby generating enough water for flushing the antenna feed line, and at the same time preventing the snow inside the groove 23 from agglomerating or icing and clogging the filter. The motor 26 can also drive the connecting rod 32 to move back and forth, so that external gas enters the interior of the airbag 5, thereby replenishing the air in the airbag 5.

[0083] The airbag 5 can reduce the vibration caused by wind impact on the outer wall of the antenna cover 3. At the same time, the airbag 5 can seal the connection between the base 4 and the antenna cover 3, which is beneficial to prevent dust and rainwater from penetrating into the interior of the antenna cover 3 and maintain the normal operation of the ceramic antenna inside the antenna cover 3.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
